6.4 General rules for using Li-Ion rechargeable batteries
Store the half-charged battery pack in a plastic container placed in a dry, cool and well ven-
tilated place and protect them from direct sunlight. The battery pack may be damaged if
stored when fully discharged. The ambient temperature for prolonged storage should be
maintained within the range of 5°C…25°C.
Charge the batteries in a cool, well-ventilated place at a temperature of 10°C ... 28°C. Mod-
ern fast chargers detect both too low and too high temperature of rechargeable batteries
and react to the situation adequately. When the temperature is too low, charging should be
prevented as it may irreparably damage the batteries. The increase in temperature of the
battery pack may cause electrolyte leakage and even its ignition or explosion.
Do not exceed the charging current, as it may result in ignition or "swelling" of the battery
pack. "Swollen" battery pack must not be used.
Do not charge or use the batteries in extreme temperatures. Extreme temperatures reduce
the lifetime of rechargeable batteries. Always observe the rated operating temperature. Do
not dispose the battery pack into fire.
Li-Ion cells are sensitive to mechanical damage. This kind of damage may cause their per-
manent damage and thus - ignition or explosion.
Any interference in the structure of Li-ion battery pack may cause its damage. This may re-
sult in the ignition or explosion.
A short-circuit of the battery poles "+" and "-" may permanently damage the battery pack or
even cause its fire or explosion.
Do not immerse Li-Ion battery in liquids and do not store in humid conditions.
If the electrolyte contained in the Lithium-Ion battery pack, contacts eyes or skin, immedi-
ately rinse the affected place with plenty of water and consult a doctor. Protect the battery
against unauthorised persons and children.
When you notice any changes in the Lithium-Ion battery pack (e.g. changes in colour, swell-
ing, excessive temperature), stop using the battery pack. Li-Ion batteries that are mechani-
cally damaged, overcharged or excessively discharged are not suitable for use.
Any misuse of the battery may cause its permanent damage. This may result in the ignition.
The seller and the manufacturer shall not be liable for any damages resulting from improper
handling Li-Ion battery pack.
